Toyo Steel are a Japanese manufacturer of pressed steel tool boxes based in Osaka.  They manufacture tool boxes for multiple other Japanese brands but also sell their products under their own Toyo Steel brand.

If you've seen similar designed tool boxes from other brands they have probably been made by Toyo.

This is the smallest cantilever style tool box that they produce.  It is 35cm x 16cm x 21.5 cm and features movable dividers in the top two trays to allow you to adjust the storage size. Have a look at Edd's instagram video (click the box below) to see how it compares, size wise, with some of the other larger cantilever toolboxes we sell. 

Its big enough to fit a normal carpenters hammer but would work equally well storing art supplies or other items.

It's also available in Olive, Red, Black and Blue (from Trusco)
